Ipod is dead how do i open it its a 8 gig nano video

The issue is that the 4th Generation iPod takes far more energy to run than your 4gb iPod. Updating the firmware has nothing to do with it. It's the amount of energy/voltage that this new 8Gig unit takes to run.
Think of it as a 4 cylinder verses an 8 cylinder engine. The 8 takes far more gas to run.

your 8 gig will work. I am assuming that you are talking about the (charging not supported) message that you get with your ipod. If this is so then you can buy an adaptor that will fix this problem. usually costs around $50

Get one of these to sole your problem. ipod change their charging circuit I found one at Walmart in the ipod accessories section. Its called the Passport home dock adapter.

- this accessory supports charging for the iPhone 3G, iPod touch (Gen 2) and iPod nano (Gen4) with most iPod docking stations
- Snaps into any iPod universal dock and accepts universal dock adapters

your battery is probably fried and most ipod chargers have an incellorator chip so you can't over charge it sorry...

Hi,

So what you can do is connect the ipod to computer (Connect it to USB Port at the rear of you desktop computer and charge it). then try these steps:

1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 8 seconds. You may need to repeat this step.

hi :) it might be your software for you ipod. try to get the latest software for your ipod :) hope it helps :)

hi :) uhmm, try to press the menu button and the center button at the same time. this happened to first ipod, a nano also, and it worked. hope this helps :) and i know how you feel emily , teehee :)

I don't know it by model number but the generation are easy to define.
A first generation nano is either black or white.  It is made out of the same material as a standard Ipod at the time.  Comes in 1 gig and 2 gig only
A second generation nano is multi colored and made from a metal case.  Similar in design to a mini.  The edges are round as well. comes in 2 gig and 4 gig.
A third generation nano is a different size than 1 and 2.  it has a bigger screen on it.  Can play videos as well.  Comes in 2 gig, 4 gig, and 8 gig as well.  

Do the 5 R's:

These are for Nano, but they apply to all iPods:

Reset, Retry, Restart, Reinstall, Restore

Remember these five basic suggestions if you have a problem with your iPod nano. If

one of the following doesn’t help, read on for solutions to specific problems.

â Reset your iPod nano. See “General Suggestions,” below.

â Retry with a different USB port if you cannot see iPod nano in iTunes.

â Restart your computer and make sure you have the latest software updates

installed.

â Reinstall iPod and iTunes software from the latest versions on the web.

â Restore your iPod nano. See “Updating and Restoring iPod Software” on page whatever.

does it work on the charger? if not, then contact apple or your dealer for more assistance or repairs.

If it works on the charger, plays music and so on, your battery is probably dead and you need a new one.
